ملخص الدراسة: The aim of this research is to produce Ultra High Performance Concrete (UHPC) in Gaza strip, using materials which are available at the local markets. Different trial mixes are used to obtain a compressive strength exceeding 120 MPa. The research includes the use of mineral admixture (silica fume), basalt aggregate, quartz sand, and […]

ملخص الدراسة: Purpose: The assessment of existing structures is becoming more and more important for social and economic reasons, while most codes deal explicitly only with design situations of new structures. The main objective of this thesis is to evaluate the current status of Islamic University buildings with degree of compatibility to international fire protection […]

ملخص الدراسة: In recent years, researches have been increasing towards studying the strengthening of concrete structures using different methods. Various studies have shown that structural concrete members such as square reinforced concrete (RC) columns can experience a significant increase in the ultimate load carrying capacity and ductility when strengthened by a concrete jacket. Despite the […]

ملخص الدراسة: This study investigates the flexural capacity, deflection and crack patterns of reinforced concrete beams repaired by application of four repair materials, Ultra High Performance Concrete, Ultra High Performance Fiber Reinforced Concrete, Ordinary Portland Concrete, and special repair materials for repair of three types of damages that can occur in construction. These include over […]

ملخص الدراسة: Fire has become one of the greatest threats to buildings. Concrete is a primary construction material and its properties of concrete to high temperatures have gained a great deal of attention. Concrete structures when subjected to fire presented in general good behavior. The low thermal conductivity of the concrete associated to its great […]

ملخص الدراسة: The usage of high strength glass fiber reinforced concrete (HSGFRC) in the construction applications has been increasing worldwide and will make an impact in Gaza Strip. Due to the limited land area available for construction, the fast growing population, bad and unstable political conditions, and the continuing wars in Gaza Strip, strong, relatively […]

ملخص الدراسة: This thesis, generally, aims to explore the potential utilization of waste crumb tires in various concrete mixes for the production of light weight and non-structural concrete to study the structural behavior of concrete, and to help partially solving environmental problem produced from disposing waste tires. As known that the strength of concrete mainly […]

ملخص الدراسة: Concrete is the most common material for human beings to use in construction. In this study, the behavior of the recycled plastic as aggregate in concrete has been investigated on compressive, tensile, and flexural strengths, weight reduction and workability. Also the impact resistance of concrete contains plastic aggregate has been carried out deeply […]
